Question

我想使用texttable将列表打印为表格。

这是我的代码：

col_types = ['t']
col_names = ['sessions/week']
col_align = ['r']
weeks_result = []
for i in range(1,53):
    col_types.append("t")
    col_names.append(str(i))
    col_align.append("r")
table = Texttable()
table.set_deco(Texttable.HEADER)
table.set_cols_dtype(col_types)
table.set_cols_align(col_align)
table.add_row(col_names)

import pdb; pdb.set_trace()
for area, results_per_week in areas_weeks_dic.items():
    weeks_result.append(area)
    for i in range(1,53):
        weeks_result.append(results_per_week[str(i)])
    print weeks_result
    table.add_row(weeks_result)
    weeks_result = []

print table.draw()

正如你在上面所看到的，我有一个断点，我用它来打印一些数据供你查看，基本上每一行都有53个元素。不知何故，这个基本代码给了我一个非常奇怪的错误，我无法破译。跟踪在下面提供。我究竟做错了什么？ ValueError的原因是什么？

Answer 1

我设法通过反复试验来解决这个问题。由于我有一个大表(+50 or so columns)，如果没有适合每个单元格的宽度信息，它就无法打印出来。

一旦我提供了一个数组，其中每个单元格的宽度都可以立即生效。

table.set_cols_width(col_width)

Python：使用texttable将列表打印为表
